Restore database on same server

For backing up databases we use VERITAS backup exec software, but when we backup databases (24) on one server it show all databases size but here I need separately, how could I get separately of each database size

ex : user database 1 size ::

user database 2 size

for office audit purposes we need to show database backup size and restored database size must be same .or if there is any other method which could resolve this issue may be appriciated .

thanks in advance
